Nested Function Issue?

I'm getting a nested function error in my code and I'm not quite sure why. I don't have the function in my for loop or in an if/else if statement. The main goal of the code is to ask the user what type of file they want read in out of the 4 options, ask how many files of that type are being read in and then ultimately displaying the data from the files in a 3D plane. Note: some of my code is straight from an example, but it shouldn't matter.

bg1 = uibuttongroup ('Visible', 'on');
bg1.Position = [.35 .45 .15 .275];
gpxbutton = uicontrol('Style', 'radio', 'String', 'gpx', 'Position',[200 275 50 30]);
csvbutton = uicontrol('Style', 'radio', 'String', 'csv', 'Position',[200 250 50 30]);
excelbutton = uicontrol('Style', 'radio', 'String', 'excel', 'Position',[200 225 50 30]);
kmlbutton = uicontrol('Style', 'radio', 'String', 'kml','Position',[200 200 50 30]);

function uibuttongroup1_SelectionChangedFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in uibuttongroup1 
% eventdata  structure with the following fields
%  EventName: string 'SelectionChanged' (read only)
%  OldValue: handle of the previously selected object or empty
%  NewValue: handle of the currently selected object
% handles    structure with handles and user data (see GUIDATA)
switch get(eventdata.NewValue,'Tag') % Get Tag of selected object.
    case 'radiobutton1'
        display('Radio button 1');
    case 'radiobutton2'
        display('Radio button 2');
    case 'togglebutton1'
        display('Toggle button 1');
    case 'togglebutton2'
        display('Toggle button 2');
end

If there are any other comments or suggestions I'd appreciate those as well.

Thanks, JD

Please show the error message.

Well, it seems you have defined a function inside a control statement. Don't do that.

Define that function somewhere else in the file and only call it inside the statement.

[Jenna Domek]

I don't see where! My only function is before the switch statement.

[José-Luis]

To find out where, please use the debugger.

This should also work:

 dbstop if error

and then run your program.

I solved my own problem, go me!

   function maingps
      bg1 = uibuttongroup ('Visible', 'on');
      bg1.Position = [.35 .45 .15 .275];
      gpxbutton = uicontrol('Style', 'radio', 'String', 'gpx', 'Position',[200 275 50 30]);
      csvbutton = uicontrol('Style', 'radio', 'String', 'csv', 'Position',[200 250 50 30]);
      excelbutton = uicontrol('Style', 'radio', 'String', 'excel', 'Position',[200 225 50 30]);
      kmlbutton = uicontrol('Style', 'radio', 'String', 'kml','Position',[200 200 50 30]);
      end
      function uibuttongroup1_SelectionChangedFcn(hObject, eventdata, handles)
      % hObject    handle to the selected object in uibuttongroup1 
      % eventdata  structure with the following fields
      %  EventName: string 'SelectionChanged' (read only)
      %  OldValue: handle of the previously selected object or empty
      %  NewValue: handle of the currently selected object
      % handles    structure with handles and user data (see GUIDATA)
      switch get(eventdata.NewValue,'Tag') % Get Tag of selected object.
          case 'radiobutton1'
              display('Radio button 1');
          case 'radiobutton2'
              display('Radio button 2');
          case 'togglebutton1'
              display('Toggle button 1');
          case 'togglebutton2'
              display('Toggle button 2');
      end
      end

thanks
